There also are three based in Australia, plus others in Malaysia. Four are based in South Africa and one is registered in Morocco. We could find none registered in India.

Operators say they carry four to five passengers, on average, and a typical mission is 500- to 600-nm long. They're comfortable flying the aircraft 2,600 to 2,800 nm, so they typically plan non-stop eastbound missions between the U.S. coasts and make one refueling stop westbound. While the aircraft has nearly 7 hr. of endurance, ATC climb and descent constraints and less than optimum routing can reduce range to 6 hr. or 2,400 nm equivalent still air distance.

Plan on burning 2,200 lb. the first hour, 1,800 lb. the second hour and 1,600 lb. during the third and subsequent hours and you'll land fat on fuel, they say.

Most corporate operators we contacted for this report say they fly the aircraft 350- to 400-hr. per year. Aircraft used by high net worth individuals and entrepreneurs typically have lower utilization. Fractional ownership and air charter aircraft may be used as much as 1,200 hr. per year.
